Listening chair height?

Thanks for the input, @cd318 ; I am one that doesn’t want to be limited to a strict sweet spot, but I have always been thinking that if there is one in my "listening room," I’d like to find it.

@erik_squires sorry for the ignorance on this subject, what is meant by mid-axis?

These are the older B&W 805s (not the Diamonds) and the tweeter is sitting about 39" above the floor. I’ve been doing some rearranging in my "listening room," and one of the things I just did was I moved a bulkier computer chair out & temporarily substituted a folding metal chair. Slouched the way I like to, my ears are probably at 44 or 45" high. That is an approximate measurement, because I took it by myself. Getting lower is not going to be hard to do, seeing as how I paid about $10 for the chair, way back when, I wouldn’t have any problem at all with whacking 5 or 6 inches off the legs. Another option is the "pillow chair" from Walmart ($98), and from what I remember of my measurements it would get me down to about 4" lower without having to slouch (the slouch is built in) and it would be a lot more comfortable.

Yes, @jerryg123  , thank you.

Thank you for clarifying that for me, @erik_squires  ; the center of my midrange driver is at 34.5" above the floor.  Being these are B&Ws, I would have to say that I am definitely too high. 

For the time being I think it is going to be cheaper/easier/quicker to bring my ear level lower than to raise the speakers (although I am already considering that option).  Tomorrow I am getting out the whiz-wheel & doing some surgery on the chair I am using right now.  I will start looking into another chair as well.  JerryG says that his IKEA chair gets his ears down to 37" which is lower than my tweeters but 2.5" higher than my midrange  drivers--I may look into those.

All speakers are different in this respect.

@roxy54  , is there a method that you would advise to experiment with this factor?   For the time being I am planning on shortening the legs of an inexpensive chair. 

@erik_squires  , thanks for the suggestions.  The speakers are currently on 24" Target stands (now wishing that many years ago I would have bought higher stands), and I'd rather not shim the stads themselves, but I could easily shim between the front of the speaker & the top of the stand.  I believe that my experimentation is going to be with shortening the legs of the inexpensive listening chair I am currently using.

@onhwy61  (that used to be one of my favorite 8-Track tape), yes, Stereophile did once review the B&W 805 Matrix model, and once upon a time I owned that copy; however, finding it would now be difficult.  I imagine that the review might be available on line, and I still have the manual that came with them and I would think that it would have all the measurements--which should I be most concerned with?

@elliottbnewcombjr  , thank you for the input.

@onhwy61  , thank you!!

"Vertically, there is very little change in the speaker's sound as long as the listener is on or below the tweeter axis. Move above the tweeter axis, however, and a deep suckout appears at the crossover frequency (fig.6). As is so often the case, this is a speaker that should never be judged by a standing listener."
